In the English version, the period at the end of the Trump realm short description wasn't being cleared on the birth realm selection screen (an earlier change made it longer and it then exceeded the length of the string used for clearing).  To fix that, use prt() to clear to the end of the line when displaying the selected realm and realm short description.  Also share more code between the Japanese and English versions for that display.
